Configuring an interface for PPPoE

Use the following procedure to configure any FortiGate interface to use PPPoE.

If you configure the interface to use PPPoE, the FortiGate unit automatically

broadcasts a PPPoE request. You can disable connect to server if you are configuring

the FortiGate unit offline and you do not want the FortiGate unit to send the PPPoE

request.

By default, the FortiGate unit also retrieves a default gateway IP address and DNS

server IP addresses from the PPPoE server. You can disable the option Retrieve

default gateway and DNS from server if you do not want the PPPoE server to

configure these FortiGate settings.

To configure an interface for PPPoE

1 Go to System > Network > Interface.

2 Choose an interface and select Modify .

3 In the Addressing Mode section, select PPPoE.

4 Enter your PPPoE account User Name and Password.

5 Clear the Retrieve default gateway and DNS from server check box if you do not want

the FortiGate unit to obtain a default gateway IP address and DNS server IP

addresses from the PPPoE server.

By default, this option is enabled.

6 Clear the Connect to Server check box if you do not want the FortiGate unit to connect

to the PPPoE server.

By default, this option is enabled.

7 Select Apply.

The FortiGate unit attempts to contact the PPPoE server from the interface to set the

IP address, netmask, default gateway IP address, and DNS server IP addresses.

8 Select Status: to refresh the addressing mode status message. Possible messages:

9 Select OK.

Adding a secondary IP address to an interface

You can use the CLI to add a secondary IP address to any FortiGate interface. The

secondary IP address cannot be the same as the primary IP address but it can be on

the same subnet.

set system interface <intf_str> config secip <second_ip>

<netmask_ip>
